Questions people ask
Compressor or desiccant dehumidifier?
Compressor models are usually cheaper to run in normal room temperatures. Desiccant models cope better in cold spaces like garages. Our pick is a compressor model for living spaces.
Is black mould dangerous?
It can affect health, especially for people with asthma or weak immune systems. Treat the cause (moisture), not just the stain.
